l'o all whom, t may concern.'

Be it known that I, AXEL MAGNUsoN, a citizen of the United States, residing at Lyndhurst. in the county of Bergen and State of New Jersey, have invented new and useful lmprovements in Lubricating Apparatus, of which the following is a specification.

My invention relates to lubricating apparatus for lubricating the stationary guides of elevators or other hoisting apparatus.

lVith the elevators in constant use the stationary guides for the cars and counterweights require frequent lubrication, and where the usual method of doing this by hand is employed, much time and labor is required. This is especially true with high speed elevators having a high rise.

An object of the present invention is to provide means for automatically lubricating the guide rails and thereby dispensing with the labor required by hand lubrication.

A f urther object of the invention is to provide means for automatically supplying a lubricant to the guides only at such time as the elevator is in operation, and cutting off the supply While the elevator is at rest.

Other objects of the invention and the exact nature thereof Will appear hereinafter.

The scope of the invention is delined'in the appended claims in which yare set forth the novel combinations of elements.

ln the accompanying drawings-Figure 1 is a fragmentary elevation vieW of an eleva tor car ivith my invention applied thereto; Fig. 2 is a part sectional elevation showing a motor and pump for supplying lubricant to the guide rails; F ig. 3 is a detail vieW of a pump; Fig. 4 is an elevation of a countervveight and guides With my invention applied thereto; Fig. 5 is a detail view of a guide and lubricating means; Fig. 6'is a sectional vieu' as indicated by the line 6-6 of Fig. 5; Fig. 7 is a diagrammatic view of the electric motors for the hoisting apparatus and lubricating devices, and the circuits for said motors; Fig. 8 is a diagrammatic vieiv of an elevator system embodying my invention; Figs. 9, 10 and 11 show modifications of the means for forcing the lubricant through the pipes.

My invention is herein shown as applied to a Well-known 'form of electric elevator comprising'a car C, a counterweight W, an

electric motor M, ahoisting drum D geared to the motor, a brake B, and cables 1 and 2 connecting the car and counterWeight respectively to the hoisting drum.v The car fra-me 3 is provided With upper guides G and lower guides G coperating with stationary guide rails A. Each guide G, as shown in detail in Figs. 5 and 6, .comprises a block 4 formed With flanges 5 extending on opposite sides of the guide rail A. The upper end of this block is hollowedout to form a cup 6 in Which may be placed absorbent material 7 such as cotton Waste or felt to hold a lubricant. Secured to the block 4 is a plate 8 provided Withy a stem 9, eX- tending into a socket 10 formed in a bracket 11, the latter being secured to the car frame 3. A screw plug 12 in the end of the socket 10 forms an adjustable abutment for a coil spring 13 bearing against the stem 9.

The lubricant is automatically supplied to the guides by means of a small pump and motor carried by the car. rl`he pump and motor are preferably placed Within a casing 114 bolted to the car frame 3. Within the casing 14 is a partition` 15 seperating the casing into two compartments 14a and 14b in which are located the motor O and the pump l? respectively. IThe motor 0 as shown is a small shunt Wound electric motor having a drive shaft 16 extending through" the partition 15 and journaled'therein. Any suitable form of pump P may be employed, and I have shown a Well known form of gear pump comprising a casing 17 in which are located interme'shing gears 18 and 19 keyed to shafts 2O and 21 journaled in the. casing 17. A spur gear pinion 22 secured to the motor shaft 16 meshes With a gear Wheel 23 pinned to the shaft 21. Within the compartment 14b is a supply of oil or other lubricatingmaterial 24. A pipe 25 extends from a point-near the bottomof the compartment to the intake side of the pump casing. A pipe 26 extends from the pressure side of the pump and is connected to a horizontal pipe 27 leading to the guides G on the car frame. Nozzles 28 are connected to the ends of the pipe 27 in position to discharge oil intothe oil cups 6 in the guides.` When the motor 0 is running the oil is drawn through the supply pipe 25 into the pump vand pumped through the pipes 26 and 27 to the guides G. The casing 14 has a removable i extended also to the lower car guides Gr but the supply through the'upper guides (i is ordinarily sufficient to keep the guide rails well lubricated. Plugs 27 may be adjusted to either throttle or entirely cut off the supply o-f lubricant to any one or more of the guides as may be desired. rl`he guide rails A for the counterweight are lubricated in the same manner as the car guide rails. The lower and upper guides G and G secured to the counterweight are substantially like the upper and lower car lguides respectively. The lower guides for the counterweight as herein shown are supplied with a lubricant from the casing 14 secured to the counterweight, within which casing is located a motor and pumping mechanism like that shown in Fig. 2. l

In Fig. 7 is showndiagrammatically an ordinary system of electrical control for the hoisting motor M and in combination therewith, means for controlling the auxiliary motors O yand O which operate the pumps on the car and counterweight respectively. This controller mechanism comprises a manual controller K withinY the car, reversing switches R and R', starting resistance S and lswitch 38 to junction 39, from thence through switch 40, conductor 41 to the motor O, and in parallel through the armature 42 and field winding 43 of the motor to the minus wires 44 and 45. The motor O therefore operates the pump to supply oil to the car guides. A parallel circuit is at the same .time established which may be traced from the junction 39 through the switch 46, conductor 47 to the motor O on the counterweights and through said motor to the minus plus wires 36, 53, switch contacts 54, armature 55, conductor 56, starting resistance S, switch contacts 57 and minus wires 52, 45. The Inotor field circuit is through conductors 36, 53, 58, field coil 59, wires 60, 61, switch contacts 62 and minus wires 52, 45. The brake coil 63 at the same time receives currentJ to lift the brake shoes, and the hoisting motor is started, for example in a direction to lift the car. When the controller lever 3l is moved onto contact 34 a circuit is closed through the magnet coil of the relay a and the latter operates to short-circuit a section of the starting resistance S and accelerate the motor in a well known manner. The controller lever 31 finally engages the contact 35 and establishes a circuit for the relay Z), causing the latter to operate and short-circuit the remainder of the starting resistance, and permit the motor to accelerate to full speed. When the controller lever is returned to central position the circ uits are opened and the motors M, O and O brought to rest. If the controller lever is moved to the right to engage the contacts 32', 33, 34 and 35, the hoisting motor M will be operated in the reverse direction and lower the car. The motors O and O will not at this time be operated, provided the switch 38 is left open as shown. One of the switches 38 and 38 is preferably left open as the operation of the auxiliary motors during the operation of the hoisting motor in one direction is usually sufficient to keep the car and counterweight guides well lubricated. Both the switches 38 and 38 may be closed, however, if desired, and the motors O and O operated whenever the motor M is running. Switches 40 and 46 are' provided in the circuits of the motor O and O' respectively, so that either or both of said motors may be disconnected whenever desired.

Fig. 9 shows a modification in which electromagnets are substituted for the motors lla nections for the magnet coils 73 are the same as described for the motors O and O', so that the magnets will be energized and force the lubricant to the guides onlyI while the car is being operated.

In Figs. 10 and 11 is shown another modification. The pump P is here inclosed in a casing 14c which may be carried by the car or counterweight. The pump is geared to a shaft 16 connected by a universal joint 77 to a shaft 78 journaled in a rod 79. The latter is operated by an electro-magnet 81 to move the friction pulley'80 into contact with the guide rail A when the magnet circuit is closed at the controller K. When certain periods of its operation, so that the lubricant is supplied only at such times and in such quantities as the varying conditions of operation require.

It will be understood that the particular form of hoisting motor and controlling mechanism herein disclosed is shown merely by way of illustration, as the present invention may readily be adapted for use with other forms of electric or other hoisting mechanism. The circuits for the motors O` and O might obviously be controlled by any of theusual forms of car controllers in use with electric, hydraulic, and other elevators, the changes necessary to connect the circuits of the motors to such controllers being within the province lof the skilled mechanic. Any suitable source of current supply may be employed. The circuits for the motors O and 0 and the magnets 70 might obviously be controlled entirely independently of the hoistingr apparatus if desired, an ordinary switch being employed to close the motor circuits .whenever it is `,desired to lubricate the guides. lt will also be understood that various specifically dieren't forms of lubricant forcing devices other than those shown might be employed and would come within the scope of the present invention.

Various changes in the details of con-y tion, and I wish therefore not to be limited to the particular construction shown.
